If any input is a string array, then the result is a string array. Each input argument can be a character array, a cell array of character vectors, or a string array. The TEXT function converts a numeric value to text and combines numbers with text or symbols.įor example, if cell A1 contains the number 23. s strcat (s1.,sN) horizontally concatenates the text in its input arguments. Use the TEXT function to combine and format strings. Learn more about using operation calculators. In many cases, using the ampersand operator is quicker and simpler than using CONCATENATE to create strings. The ampersand (&) calculation operator lets you join text items without having to use a function.įor example, =A1 & B1 returns the same value as =CONCATENATE(A1,B1). Use the ampersand & character instead of the CONCATENATE function. #NAME? usually means there are quotation marks missing from a Text argument. The #NAME? error appears instead of the expected result. ![]() The string "Hello " has an extra space added. For example: =CONCATENATE("Hello ", "World!"). For example: =CONCATENATE("Hello", " ", "World!").Īdd a space after the Text argument. ![]() There are two ways to do this:Īdd double quotation marks with a space between them " ". Add extra spaces as part of the CONCATENATE formula. Without designated spaces between separate text entries, the text entries will run together. Numbers don't need to have quotation marks. For example: Excel will display =CONCATENATE("Hello ""World") as Hello"World with an extra quote mark because a comma between the text arguments was omitted. Use commas to separate adjoining text items. Joins the same items as the previous example, but by using the ampersand ( &) calculation operator instead of the CONCATENATE function. Joins three things: the string in cell B3, a string consisting of a space with ampersand and another space, and the value in cell C3. Joins three things: the string in cell C2, a string with a comma and a space character, and the value in cell B2. Joins three things: the string in cell B2, a space character, and the value in cell C2. ![]() The result is Stream population for brook trout species is 32/mile. To use these examples in Excel, copy the data in the table below, and paste it in cell A1 of a new worksheet.Ĭreates a sentence by joining the data in column A with other text. You can have up to 255 items, up to a total of 8,192 characters. The item can be a text value, number, or cell reference.Īdditional text items to join. =CONCATENATE("Stream population for ", A2, " ", A3, " is ", A4, "/mile.") This is because CONCATENATE may not be available in future versions of Excel. Although the CONCATENATE function is still available for backward compatibility, you should consider using CONCAT from now on. Note to others: Do NOT use eval to solve trivial tasks like this that can be easily avoided using simpler, more efficient code.Important: In Excel 2016, Excel Mobile, and Excel for the web, this function has been replaced with the CONCAT function. If you spend a few hours reading those links and still have any question, please ask. If you are not sure why, then read all of the linked threads in my tutorial: the more you understand about the MATLAB JIT engine, the more you will understand why both creating and accessing are equally bad. Regardless of what tool or method, whether creating or accessing, all of them will make code slow, complex, and buggy. This is simply inherenet in how the JIT engine works. The problems of eval, evalin, assignin, load (without an output argument), etc are not specific to just creating variables, but also to accessing them. "I thought that here, eval is not used to create a set of data, as mentioned in the documentation." mat files into output varaibles and avoid the whole problem. In which case it is trivial to load those. varTypes specifies the data types of the variables. sz is a two-element numeric array, where sz (1) specifies the number of rows and sz (2) specifies the number of variables. "that the author of the question has got some mat-files with differently named data" T table ('Size',sz,'VariableTypes',varTypes) creates a table and preallocates space for the variables that have data types you specify. This is how I ended up storing the onsets for the existing false_onsets variables using a structure: if ~isempty(listen_false_index)įalse_onsets_lis (1,ii)=onsets (1,baseline_false_index(ll)) įalse_duration_base=zeros(1,length(baseline_false_index)) As I told you, not all participants have all false_onsets variables. I actually created the false_onsets variables with a loop for each participant. ![]() Thanks Stephen for providing this solution and warning against the use of eval function.
